  REPORT 
  OF 
  COMMISSIONER 
  OF 
  PISH 
  AND 
  FISHERIES. 
  

  

  ville 
  the 
  previous 
  winter. 
  They 
  appeared 
  to 
  be 
  very 
  healthy 
  for 
  a 
  time, 
  

   but 
  later 
  in 
  the 
  summer 
  they 
  were 
  attacked 
  by 
  a 
  parasitic 
  trematode, 
  

   which 
  appeared 
  in 
  large 
  numbers, 
  especially 
  on 
  their 
  fins 
  and 
  jaws. 
  

   The 
  mortality 
  resulting 
  aggregated 
  over 
  26,000, 
  leaving 
  only 
  10,411 
  for 
  

   distribution 
  in 
  November. 
  No 
  other 
  species 
  were 
  attacked 
  by 
  this 
  

   parasite, 
  though 
  all 
  were 
  kept 
  in 
  the 
  same 
  locality 
  and 
  under 
  the 
  same 
  

   conditions. 
  A 
  large 
  percentage 
  of 
  fish 
  was 
  hatched 
  from 
  the 
  consign 
  

   ment 
  of 
  Swiss 
  lake-trout 
  eggs 
  received 
  from 
  Switzerland 
  in 
  February, 
  

   189G. 
  A 
  few 
  of 
  these 
  were 
  held 
  over 
  and 
  distributed 
  in 
  the 
  spring 
  of 
  

   1807, 
  but 
  the 
  bulk 
  of 
  them 
  were 
  disposed 
  of 
  in 
  the 
  fall. 
  

  

  Sfeelhead 
  trout. 
  — 
  The 
  fish 
  on 
  hand 
  at 
  the 
  beginning 
  of 
  the 
  year 
  were 
  

   carried 
  through 
  the 
  summer 
  with 
  small 
  loss, 
  and 
  all 
  of 
  them 
  with 
  the 
  

   exception 
  of 
  200 
  were 
  distributed 
  during 
  the 
  fall. 
  These 
  were 
  placed 
  

   in 
  one 
  of 
  the 
  new 
  ponds 
  for 
  domestication, 
  and 
  191 
  of 
  them 
  survived 
  to 
  

   the 
  close 
  of 
  the 
  year. 
  From 
  a 
  consignment 
  of 
  eggs 
  received 
  in 
  April 
  

   94,811 
  fry 
  were 
  hatched 
  ; 
  all 
  but 
  10,000 
  of 
  these, 
  which 
  have 
  been 
  retained 
  

   for 
  rearing, 
  were 
  distributed 
  in 
  local 
  waters 
  during 
  May 
  and 
  June. 
  

  

  Quinnat 
  salmon. 
  — 
  The 
  quinnat 
  salmon 
  on 
  hand 
  at 
  the 
  beginning 
  of 
  

   the 
  year 
  were 
  the 
  result 
  of 
  a 
  consignment 
  of 
  eggs 
  received 
  from 
  Baird 
  

   in 
  December, 
  1895. 
  They 
  were 
  carried 
  through 
  the 
  summer 
  without 
  

   material 
  loss, 
  and 
  in 
  November 
  7,062 
  yearlings 
  were 
  liberated 
  in 
  local 
  

   waters. 
  During 
  the 
  fall 
  200 
  of 
  them 
  were 
  transferred 
  to 
  the 
  aquarium 
  

   in 
  Washington 
  and 
  held 
  until 
  the 
  following 
  spring, 
  when 
  they 
  were 
  

   sent 
  to 
  Nashville 
  for 
  exposition 
  purposes. 
  Another 
  lot 
  of 
  200 
  was 
  

   retained 
  at 
  the 
  station 
  until 
  the 
  following 
  June, 
  when 
  they 
  were 
  liber- 
  

   ated, 
  with 
  a 
  loss 
  of 
  only 
  4, 
  in 
  local 
  waters. 
  In 
  December, 
  1896, 
  a 
  con- 
  

   signment 
  of 
  1,440,000 
  eggs 
  was 
  received 
  from 
  Battle 
  Creek, 
  Cal. 
  Some 
  

   slight 
  mishaps 
  befell 
  them 
  and 
  it 
  became 
  necessary 
  to 
  crowd 
  them 
  

   considerably 
  on 
  account 
  of 
  lack 
  of 
  space, 
  but 
  notwithstanding 
  these 
  

   adverse 
  circumstances 
  1,265,594, 
  or 
  87 
  per 
  cent, 
  of 
  them 
  hatched. 
  Of 
  

   these, 
  789,000 
  were 
  deposited 
  in 
  the 
  Penobscot 
  and 
  its 
  branches 
  above 
  

   Oldtowu, 
  77,449 
  were 
  liberated 
  in 
  local 
  waters, 
  and 
  50,000 
  were 
  trans- 
  

   ferred 
  to 
  the 
  Maine 
  Commission, 
  making 
  a 
  total 
  distribution 
  of 
  916,449; 
  

   250,000 
  were 
  reserved 
  at 
  the 
  station 
  to 
  be 
  reared 
  and 
  distributed 
  in 
  the 
  

   fall, 
  and 
  at 
  the 
  close 
  of 
  the 
  year 
  they 
  were 
  in 
  excellent 
  condition. 
  

  

  The 
  total 
  amount 
  of 
  food 
  used 
  consisted 
  of 
  42,746 
  pounds 
  of 
  butcher's 
  

   offal, 
  beef 
  blood, 
  and 
  horse 
  carcasses, 
  the 
  original 
  cost 
  of 
  which 
  was 
  

   $592.25, 
  the 
  additional 
  expense 
  of 
  freight 
  and 
  drayage 
  aggregating 
  

   $105.97. 
  This 
  large 
  increase 
  in 
  cost 
  and 
  amount 
  of 
  food 
  was 
  due 
  to 
  

   the 
  increased 
  number 
  of 
  fish 
  carried; 
  and 
  it 
  was 
  learned 
  by 
  experiment 
  

   that 
  quinnat 
  salmon 
  require 
  a 
  larger 
  amount 
  of 
  food 
  than 
  Atlantic 
  

   salmon 
  and 
  other 
  fishes. 
  

  

  The 
  stock 
  of 
  fry 
  held 
  for 
  distribution 
  in 
  the 
  fall 
  consisted 
  of 
  240,000 
  

   Atlantic 
  salmon, 
  2,167 
  domesticated 
  Atlantic 
  salmon, 
  2,295 
  landlocked 
  

   salmon, 
  250,000 
  quinnat 
  salmon, 
  1,894 
  Scotch 
  sea 
  trout, 
  and 
  10,000 
  steel- 
  

   head 
  trout.
